In multiviewtest: Hypothesis Tests for Association Between Subgroups in Two Data Views

Description

Generates data from a stochastic block model for multiple network data views with n observations and two views.

Usage

mv_sbm_gen(n, Pi, theta1, theta2, sparse = FALSE)

Arguments

n	number of observations
Pi	K1 x K2 matrix where the (k, k')th entry contains the probability of an observation belonging to community k in View 1 and community k' in View 2
theta1	K1 x K1 matrix containing the between-community edge probabilities for View 1
theta2	K2 x K2 matrix containing the between-community edge probabilities for View 2
sparse	If true, return data views in sparseMatrix format

Value

A list containing the following components:

data	A list with two items: the n x n view 1 adjacency matrix and the n x n view 2 adjacency matrix
communities	A list with two items: the view 1 community memberships and the view 2 community memberships

Examples

# 50 draws from a stochastic block model for two network data views 
# where the communities are dependent
n <- 50
Pi <- diag(c(0.5, 0.5))
theta1 <- rbind(c(0.5, 0.1), c(0.1, 0.5))
theta2 <- cbind(c(0.1, 0.5), c(0.5, 0.1))
